Yes, we talked about it if you look back a page or 2...

So this is a full spectrum CFL that includes UVB or just a UVB light? So, if you are flowering now are you using this plus 2700k CFLs or including some 6500k bulbs also?

Is that bulb enough UVB for multiple plants or are you only using it for a single plant... I take it you place it somewhere above the cola?

Edit: I'm very interested in adding UVB and wondering if it's something I could/should just do in the last few weeks of flower to force extra production before harvest of it it's important to add the light at the start of flower. Again though, I'm not exactly clear on the type of bulb, number to use, or where to place it. It seems like a CFL UVB bulb would only hit a small portion of the plant. Rotating the light around the canopy is a possibility I suppose but is a couple hours of UVB a day per section of plant enough- assuming I"m able to rotate it that often the final couple weeks?

Thanks.

Speaking as a beginner, it seems like the next major improvement in lighting is some sort of setup that includes the hybrid bulb plus some kind of UVB light under the same roof that is enough to penetrate a couple feet into the canopy. It seems like right now people are having to retrofit and rig UV in a way that doesn't really cover the plants... I wish I could see some pics of setups that incorporate UVB.
